Hello , I don't want to disturb you , I just want to get my answers , 
My question is , I am not using any functions or storage , just using db and users auth , is 1.7MB bandwidth in 3days normal ?
Also , deleting old data from db can reduce bandwidth consumption or not ??
Please answer 
Thanks
  TL;DR
 Developer is questioning if 1.7MB bandwidth usage in 3 days is normal without using functions or storage, only utilizing db and user authentication. Questioning if deleting old data from db can reduce bandwidth consumption.
